1. Scrubbing Technology N. Maximova, Puu-0.4400 Wet scrubbers remove particles by capturing them in liquid droplets. Wet scrubbers remove pollutant gases by dissolving or absorbing them into the liquid. Wet scrubbers that remove gaseous pollutants are referred to as absorbers. the packed tower and the plate tower Dry scrubbers use spray dryer absorption and dry injection adsorption. 1
